Ansel: Complete Pipeline Overhaul
The article discusses a significant overhaul of the Darktable pipeline aimed at improving RAM usage and performance. The previous cache system was ineffective, leading to unnecessary recomputation of image data. The redesign focuses on making data management more visible and efficient, resulting in better overall performance.
- ▪Darktable's previous RAM cache was underused and inefficient, causing repeated computations.
- ▪The overhaul aims to redesign the software's architecture for better data lifecycle management.
- ▪Improvements in performance are expected to exceed previous optimizations made within individual modules.

Opening excerpt (first ~120 words) tap to expand
Complete pipeline overhaul March 29, 2026 — April 6, 2026 — Development — EnglishLanguagesFrançaisDeutschEspañolItalianPolishPortuguêsUkrainianDutch— Since I started using Darktable, circa 2012, I have always been surprised by how little RAM it used. People think it is a good thing that an application uses the memory sparingly, and that is surely true if we talk about your desktop environment. But talking of a production software that does heavy pixel rendering on images from 12 to 54 Mpixels, this means the same heavy computations are done again and again instead of being saved to be reused later. That’s what a cache is for : avoiding expensive computations.
